Understanding the Strength of Solar Panels

Solar panels are designed to withstand a specific amount of weight, but it is important to understand their strength limitations before considering walking on them.

How much weight can a solar panel handle?

Solar panels are designed to endure the elements and withstand a certain amount of weight. Typically, they can tolerate around 50 pounds per square foot, with some models capable of supporting up to a maximum of 75 pounds.

This capacity allows them to cope with heaps of snow or debris that might accumulate on their surface. However, despite this impressive strength, human footsteps exert concentrated pressure, which could damage the delicate tempered glass surface more easily than distributed weights like snow or debris.

Additionally, flexible solar panels are particularly vulnerable to cracking under undue pressure as they boast less structural rigidity than fixed ones. Therefore, refraining from stepping or walking on solar panels is always advisable for their longevity and optimal efficiency.

The Risks of Walking on Solar Panels

Walking on solar panels can potentially damage the panels and pose a risk of electrocution. Find out why avoiding stepping on solar panels is important and how to identify damage and ensure proper maintenance.

Potential for panel damage

Despite their durable exterior, solar panels can sustain considerable damage under the pressure of walking. Stepping directly on them might cause the glass to crack or pop out from its frame.

Both fixed and flexible solar panels are susceptible to this kind of damage; however, flexible ones prove even more fragile. Walking on these units also introduces risks beyond breakage, including potential slips due to the panel’s smooth surface.

This suggests that whilst a photovoltaic system is strong enough to hold an average human weight, it can’t handle concentrated pressure from our footsteps without negatively risking power output efficiency or energy production capacity.

Risk of electrocution

Solar panels generate electricity, and mishandling could lead to a dangerous electric shock. The risk heightens when the panel is damaged or wet.

Lightning strikes may also increase these dangers as solar setups usually lack adequate protection against such natural occurrences. Always ensure precautions before any interaction with solar panels to prevent electrocution hazards.

Identifying Damage to Solar Panels

Cracks, scratches, and other factors can indicate potential damage to solar panels. Read on to learn how to identify and address these issues.


Cracks in solar panels can be a serious issue. They not only affect the panels’ aesthetics but also their performance. Even small cracks can lead to water damage and decrease the panels’ efficiency over time.

Cracks are often caused by factors like temperature changes, hailstorms, or even improper installation. It is important to regularly check your solar panels for any signs of cracking and address them promptly to ensure optimal performance and longevity.

Remember that attempting to walk on cracked solar panels can worsen the damage and pose a safety risk.


Walking on solar panels can easily scratch or damage the glass surface. These scratches may initially seem harmless, but they can significantly impact the panels’ performance.

Scratches can lead to reduced efficiency and power output as they disrupt the flow of sunlight onto the photovoltaic cells. Not only that, but scratches compromise the integrity of the glass, making it more susceptible to cracking or breaking in harsh weather conditions.

Furthermore, scratched panels are harder to self-clean, which can further reduce their overall performance over time. It’s important to be cautious and avoid any actions that could potentially scratch or damage your solar panels.

Other factors

Solar panel damage can occur due to factors other than cracks and scratches. For example, improper installation or mounting can weaken the panel structure, making it more susceptible to damage.

Additionally, exposure to extreme temperatures or harsh weather conditions can affect the efficiency and lifespan of solar panels. Considering these factors and ensuring proper maintenance and care for your solar panels to maximise their performance and longevity is crucial.

Regular inspections by professionals can help identify potential issues early on and prevent further damage or safety risks.
